VEHICLE-WHEEL RIM.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed. December 3, 1909. Serial No. 531,263.

Be it known that 1, JOHN M. Anonnrnn, a citizeniof the United States, residing at Sharon Center, in the county of Medina and State of Ohio, have invented new and use ful Improvements in Vehicle-Wheel Rims, of which the following is a specification.

This invention relates to vehicle wheel rims for holding elastic tires, more especially the outer shoes of doubletube pneumatic tires, and the object is primarilyto provide a wheel rim'having detachable tireretaining means for holding theouter shoe of an inextensible selvage edge type of tire provided with detachable'locking means for securely holding one of the'tire-retaining means, said rim after the removal of the tire-retaining means for the inextensible selvage edge tire constituting a supporting medium for an auxiliary rim carrying a previously-inflated tire, preferably. of the clencher type and-held in position by the same means previously utilized for sustaining the tire-retaining meansfor the inextensible'selvagc edge type of tire; that is to say, either type oftire may be alternately mounted upon said'rim and held in position by a locking device common to both.

A. further object of this invention is to provide a locking device for holding the tire-retaining means for either type of tire alternately in position against circumferential movement or creepmg, said locking device provided with means for-preventing its unintentional displacement or removal from its locking position while holding the detachable portion of the rim in cooperating relation with the fixed portion.

With the foregoing and other objects in view, the invention consists in the novel con-. struction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accompanying drawings which form .a part hereof wherein is shown the pre ferred embodiment of the invention, but it is to be understood that'changes, variations .and modifications can be resorted to which comewithin the scopeofthe claims hereunto appended I In the drawings, ence numerals indicate like parts in the dif- "ferent figures: Figure 1 is a view in trans-v in which similar referverse section of the rim-portion of a 've-x hiclewheel with a tire of the inextensible selvage edge type mounted thereon and with the locking means for the tire-retaining means in cooperating relation therewith.

Fig. 2 is a view similar to the rim shown in Fig. 1 with an auxiliary rim mounted there on, said tire-holding rim held in position by the locking means shown in Fig. 1. Fig. 3 is a longitudinal, sectional view of Fi 2 on line X thereof. Fi 4; is an inverte plan showing. the under ace of the'locking ring. Fig. 5 1s a erspective view of the ends of the split loo ing ring separated from each other to better illustrate the construction thereof, and, 'Fig. 6 is a perspective'view of y the type of rim and tire-retaining means shown in Fig; 1 illustrating the registering notches therein. Referring to the drawings in detail, the reference numeral 1 denotes a continuous annular rim rovided with a seat 2 for a tire and provi ed along one, side edge with an outwardlyrextending flange 3 constituting an abutment and on the other side with an inwardly-extending flange 4: having a laterally-extending annularly-formecl face 5, the outer portion .6 of which constitutes a seat for a purpose to be hereinafter described.

'Mounted'on the seat 2 of the rim 1 is a -tire-retainin rin 7 the lateral faces of which are tor-me upon curvilinear lines, one of which is adapted to abut against and engage the flange 3 of the rim. Mounted on the seat 6 of the ridge 5 is a second ring 8 with the inner lateral -face formed tocor "respond with the inner lateral face'of the ring '7 and both of which are arrangedto constitute supporting (means for the sides of a tire 9' of the inextensible selvage edge type, as shown in the drawings. The inner portion ofthe ring 8 extends inwardly, and

.as before stated, seats on the seat. 6 of the face 5 and'with its inner lateral face bearing against the faceof the, depending flange &. The ring 8 is held in position. through the medium of a split expansible U-shaped locking ring 10 provided with a groovevor channel adapted, to-inclose the'flange 4,- face 5 andinwardly-extending portion of the ring 8 for locking it securely in position? The split locking ring 10 isadapted to be sprun over the described portionsof the an tire-retaining element by 'beingifirst contracted, and is held lace when seated by its inherent resiliency; in endeavoring to rec the seat 2 of the rim 1.

through the medium of pin 12. 'This member 11 is preferably disposed in the groove adjacent to the severed ends of the ring 10 so as to overlap and project into the opposing end thereof and is also of such a size and length that when the split ring 10 is sprung over the inwardly-extending flange 1 and face 5, the member 11 will engage in the registering'notches 22 and constitute a lock for preventing longitudinal movement of the ring 8 with respect to the rim. The inner face of the member 11 is provided with an inwardlyextending lug 21 arranged'to extend beyond the inner surface of the ring 10 adjacent to one of the severed ends thereof. The ring 10 is preferably severed on a line oblique to the axis of the wheel and the severed end opposing the end which carries the member 11 is provided with a longitudinal slot 14 to receive the lug 21 when the ring is in operative position. The lug 21. is provided with a transverse aperture 13 to receive some device such as a cotter-pin 15 for locking the slotted end of the'ring against unintentional dis placement.

In Fig. 2- is shown a supplemental tire rim 16, preferably previously supplied with an inflated clencher tire 17. This clencher tire 17 is provided with the usual inturned clencher flanges 18 for holding the base portion of the shoe ofthe tire and is of such a diameter that when passed laterally onto the rim 1 it will be supported 011 one side by the outwardly-extending flange or 'abutment 3, and on the other side by an inwardly-extending circumferential face 19 which bears or rests upon the outer face of The clencher rim 16 is prq-ivided with an inwardly-extendin flange 20 adapted to seat on the face 5 an be hfeld in position by the locking ring 10 in the same manner as has been described with reference to the tire-holding ring 8 heretofore mentioned.

The inwardly extending flange 20 of the supplemental. rim 16 is also similarly provided with a notch arranged to register with the notch in the inwardly-extending flange 4 to receive the member 11 for loclcing the auxiliary rim 16 against circuniferential movement.

From the foregdiug it will be seen that in using this device the operator of the vehicle may carry an extra tire rim supplied with an inflated clencher tire, and when for any reason the inextensible selvage edge tire originally placed on the rim 1 has been punctured or so badly damaged as to be unserviceable, the selvage edge type of tire may be removed, together with its tire-re taining rings 7 and 8, after which the clencher rim with its previously-inflated tire may be passed laterally onto and seat upon the rim 1 and be locked in position through the medium of the self-expansible grooved ring 10, and at the same time-the member 11 carried by the ring will effectually lock the clencher tire rim against circumferential movement with respect to the Wheel rim, and as the clencher tire is securely held by the clencher rim the danger of the tire creeping in its channel is eliminated.

I claim:
